Both the Karma and the 458 are known for being great kindling. Not sure I would store them in a tinder-box garage. lol.
Once you get past the expense of creating a space for that purpose, nothing about the garage in the OP is particularly over the top. Looks tastefully done from the photos. Car elevators aren't that uncommon and from the text it looks to be a practical solution to the limitation imposed by the municipal codes.The car elevator is a bit over the top, IMHO.
